GS. Tyler Cowen trong bài viết này cho rằng các nền kinh tế phát triển gần đây tăng trưởng trì trệ một phần là do thiếu các cuộc chiến tranh lớn. Chiến tranh có thể tốt cho phát triển kinh tế, theo GS. Cowen là vì mấy lý do chính:

– Chiến tranh làm tăng chi tiêu, đầu tư công của chính phủ

– Chiến tranh tạo ra thêm việc làm

– Quan trọng nhất, sự cấp bách của chiến tranh khiến các chính phủ quyết tâm đầu tư vào khoa học và công nghệ, nhanh chóng mang lại các đột phá hơn, điều có lợi cho tăng trưởng kinh tế, nhất là trong dài hạn.

Ngoài ra chiến tranh cũng có xu hướng tăng cường trật tự xã hội, kích thích các chính phủ hành động nhanh chóng và hiệu quả để đối phó với nguy cơ từ bên ngoài.

Tuy nhiên tác giả cũng cho rằng ngày nay công nghệ đã làm cho chiến tranh trở nên mang tính hủy diệt hơn nhiều, và người ta dường như chấp nhận đánh đổi tăng trưởng kinh tế chậm để đổi lấy hòa bình.

The Lack of Major Wars May Be Hurting Economic Growth

Tyler Cowen

The continuing slowness of economic growth in high-income economies has prompted soul-searching among economists. They have looked to weak demand, rising inequality, Chinese competition, over-regulation, inadequate infrastructure and an exhaustion of new technological ideas as possible culprits.

An additional explanation of slow growth is now receiving attention, however. It is the persistence and expectation of peace.

The world just hasn’t had that much warfare lately, at least not by historical standards. Some of the recent headlines about Iraq or South Sudan make our world sound like a very bloody place, but today’s casualties pale in light of the tens of millions of people killed in the two world wars in the first half of the 20th century. Even the Vietnam War had many more deaths than any recent war involving an affluent country.

Counterintuitive though it may sound, the greater peacefulness of the world may make the attainment of higher rates of economic growth less urgent and thus less likely. This view does not claim that fighting wars improves economies, as of course the actual conflict brings death and destruction. The claim is also distinct from the Keynesian argument that preparing for war lifts government spending and puts people to work. Rather, the very possibility of war focuses the attention of governments on getting some basic decisions right — whether investing in science or simply liberalizing the economy. Such focus ends up improving a nation’s longer-run prospects.

It may seem repugnant to find a positive side to war in this regard, but a look at American history suggests we cannot dismiss the idea so easily. Fundamental innovations such as nuclear power, the computer and the modern aircraft were all pushed along by an American government eager to defeat the Axis powers or, later, to win the Cold War. The Internet was initially designed to help this country withstand a nuclear exchange, and Silicon Valley had its origins with military contracting, not today’s entrepreneurial social media start-ups. The Soviet launch of the Sputnik satellite spurred American interest in science and technology, to the benefit of later economic growth.

War brings an urgency that governments otherwise fail to summon. For instance, the Manhattan Project took six years to produce a working atomic bomb, starting from virtually nothing, and at its peakconsumed 0.4 percent of American economic output. It is hard to imagine a comparably speedy and decisive achievement these days.

As a teenager in the 1970s, I heard talk about the desirability of rebuilding the Tappan Zee Bridge. Now, a replacement is scheduled to open no earlier than 2017, at least — provided that concerns about an endangered sturgeon can be addressed. Kennedy Airport remains dysfunctional, and La Guardia is hardly cutting edge, hobbling air transit in and out of New York. The $800 billion stimulus bill, in response to the recession, has not changed this basic situation.

Today the major slow-growing Western European nations have very little fear of being taken over militarily, and thus their politicians don’t face extreme penalties for continuing stagnation. Instead, losing office often means a boost in income from speaking or consulting fees or a comfortable retirement in a pleasant vacation spot. Japan, by comparison, is faced with territorial and geopolitical pressures from China, and in response it is attempting a national revitalization through the economic policies of Prime Minister Shinzo Abe.

Ian Morris, a professor of classics and history at Stanford, has revived the hypothesis that war is a significant factor behind economic growth in his recent book, “War! What Is it Good For? Conflict and the Progress of Civilization From Primates to Robots.” Morris considers a wide variety of cases, including the Roman Empire, the European state during its Renaissance rise and the contemporary United States. In each case there is good evidence that the desire to prepare for war spurred technological invention and also brought a higher degree of internal social order.

Another new book, Kwasi Kwarteng’s “War and Gold: A 500-Year History of Empires, Adventures, and Debt,” makes a similar argument but focuses on capital markets. Mr. Kwarteng, a Conservative member of British Parliament, argues that the need to finance wars led governments to help develop monetary and financial institutions, enabling the rise of the West. He does worry, however, that today many governments are abusing these institutions and using them to take on too much debt. (Both Mr. Kwarteng and Mr. Morris are extending themes from Azar Gat’s 820-page magnum opus, “War in Human Civilization,” published in 2006.)

Yet another investigation of the hypothesis appears in a recent working paper by the economists Chiu Yu Ko, Mark Koyama and Tuan-Hwee Sng. The paper argues that Europe evolved as more politically fragmented than China because China’s risk of conquest from its western flank led it toward political centralization for purposes of defense. This centralization was useful at first but eventually held China back. The European countries invested more in technology and modernization, precisely because they were afraid of being taken over by their nearby rivals.

But here is the catch: Whatever the economic benefits of potential conflict might have been, the calculus is different today. Technologies have become much more destructive, and so a large-scale war would be a bigger disaster than before. That makes many wars less likely, which is a good thing, but it also makes economic stagnation easier to countenance.

There is a more optimistic read to all this than may first appear. Arguably the contemporary world is trading some growth in material living standards for peace — a relative paucity of war deaths and injuries, even with a kind of associated laziness.

We can prefer higher rates of economic growth and progress, even while recognizing that recent G.D.P. figures do not adequately measure all of the gains we have been enjoying. In addition to more peace, we also have a cleaner environment (along most but not all dimensions), more leisure time and a higher degree of social tolerance for minorities and formerly persecuted groups. Our more peaceful and — yes — more slacker-oriented world is in fact better than our economic measures acknowledge.

Living in a largely peaceful world with 2 percent G.D.P. growth has some big advantages that you don’t get with 4 percent growth and many more war deaths. Economic stasis may not feel very impressive, but it’s something our ancestors never quite managed to pull off. The real questions are whether we can do any better, and whether the recent prevalence of peace is a mere temporary bubble just waiting to be burst.
